New Jersey Democrats and Republicans each picked men who grew up in Union City to be their parties' nominees for U.S. Senate on Tuesday.

And while Democratic incumbent Sen. Bob Menendez and Republican challenger Bob Hugin may agree on some things — Hugin actually gave the maximum allowed to Menendez's last re-election campaign — they've already taken hard swings at each other, and things are likely to get nastier as the year goes on. In one poll previewing the November race, Menendez led Hugin 28 percent to 24 percent, with 46 percent undecided, in a Fairleigh Dickinson University poll of 856 registered voters taken May 16-21.

Here's a look at who they are, and what they're saying:

Republican challenger Bob Hugin

Republican Senate candidate Bob Hugin talks about his New Jersey roots and why he decided to get into the race against Democratic Sen. Bob Menendez.

1999-18, Celgene Corp.: started as senior vice president and chief financial officer; became president and chief operating officer 2006; chief executive officer, 2010; chairman of the board, 2011; executive chairman, 2016; retired in January

The committee said he broke Senate rules and disclosure laws for accepting undisclosed trips on his friend and top contributor's private jet, as well as vacations at resorts, while advocating for the donor/friend's personal and business interests. That advocacy involved a port security contract in the Dominican Republic, Medicare rules for administering multiple doses from single-use vials, and visa applications by the donor/friend's foreign girlfriends.

Drug prices: Menendez blasts Hugin's record at Celgene Corp., especially the company's increases in the price of cancer drugs, its efforts to thwart the production of cheaper generics, and a $280 million settlement of a whistleblower lawsuit alleging the firm improperly marketed some drugs.

Cost of living in New Jersey: Hugin says Menendez has not done enough to combat the high cost of living in New Jersey or fight a provision in the tax law that put a $10,000 cap on the federal deduction for state income and local property tax payments. Hugin points to Menendez's 25-year career in Washington at a time the state perennially ranked near the bottom of the list of how much federal taxes paid to Washington by residents came back through federal spending.

President Trump: Menendez says despite Hugin's claims to be independent, he was a Trump delegate at the Republican Party convention in 2016 and gave $100,000 to a political fund that helped Trump get elected.

Hugin about himself

"This wasn’t part of my life’s plan. ... I am one of the most fortunate people, I’m living the American dream ... I’m a caring person, but I’m an outcomes-oriented person that says, ‘Let’s be independent, let’s achieve results.’ ... I think New Jersey’s going to get somebody who cares about them and is going to say, ‘I’m glad to be held to a standard of behavior, personally, with integrity and ethics, but also to outcomes and results."

Hugin about Menendez

"The Senate ethics committee — bipartisan, unanimously, with Washington's greatest lawyers — drew the conclusion very clear: He violated the law, he abused the power of his office, he disgraced the Senate. ... My wife and I and my whole family actually thought about it and we were frankly offended that Senator Menendez was going to be re-elected virtually unopposed if I didn't step in. And we just felt this was wrong for America, wrong for New Jersey, wrong for democracy."

Hugin about Trump

"I was very very concerned about the stagnation in Washington and I did see Hillary Clinton as part of that stagnation and I saw Donald Trump as a disrupter. I think it’s gone too far to dysfunctional things in some areas, so I’m not a fan of a lot of things that have [been] done, but I was very supportive of disruption and I think we needed the change in Washington.

"And the reason I’m running now is to say yes, we had stagnation, we have some disruption, but we have too much dysfunction too, and we need people who have a track record of being thoughtful, reasonable, working with others collaboratively to find solutions."

Menendez about himself

"When New Jerseyans look at our record of success and advocacy for them, they will decide this is someone who is standing up and fighting for them. ... When the spotlights were gone, I was in the midst of still fighting for Sandy victims, years after. When the government denied them the money that I had fought to get them in the first place as part of the package that we got for Sandy recovery, I went to work. ... I wrote the national Autism Cares legislation that helps New Jersey families who have a loved one on the autism spectrum and also tries to find greater research to find cures. ... 800,000 New Jerseyans now have health care that did not have it prior to the Affordable Care Act. I think that those who now enjoy health care and those who no longer suffer exclusion because of pre-existing conditions, lifetime caps and other discrimination that existed prior to the law will say, 'This is someone who understands the challenges that I face.' "

Menendez about Hugin

"If you look at everything the Trump administration is doing, whether purposely or not, and I think it's purposely, it constantly attacks New Jerseyans. The last thing I think you need to do is to send another Republican to the Senate who supported Donald Trump, who was a Trump delegate, and who ultimately gave him thousands and thousands of dollars to help him become president of the United States when this guy has us in his sights. ...

"I’ll stake my judgment in fighting for the things I’ve fought for for New Jersey families compared to the judgment of Bob Hugin, who ripped off cancer victims by time and time and time again raising the cost of one drug. ... You don’t have to keep raising the cost of a singular cancer drug three times in one year. That’s not about recoupment, that’s about profit. Profit that is obscene. Profit that comes on the back of cancer patients. Profit that is unconscionable."

Menendez about admonishment

"I had a different understanding of disclosure under the rules. I thought that many of the provisions were excluded under the friendship exception. And so did my staff, and that’s why those didn’t get reported in the first place. And when it has come to my attention that in fact that was a wrong interpretation, we have done the appropriate things.

"I don’t think it was wrong at the end of the day to fight to make this country safer, which I always had under port security. I don’t think it’s wrong to try to make drugs more affordable, which is what I was doing in my advocacy for multi-dosing, which is now the subject of bipartisan legislation in the Senate between Senator Grassley and Senator Klobuchar and others, to do exactly that.

"And I have always supported those who have the right, if they qualify to visit the United States. So my advocacy in all those regards are within the historical context of things that I’ve done in the same regard."
